Hello,
Please remember this is beta version, everything is currently being setup. It takes time.
I can answer your question: it doesn't fall under GDPR as data is anonyme, there's no personal data.
The software only sends Operating system version, software version, software name, and this is all. All we need is usage count and it's stored as number per days in database.
We own the database as well.
I hope this answers the question.
Thanks,
